AERIAL-CABLE GUIDE.

Specification of Letters Patent. I t t May 25, 192

Application filed. February 8, 1919. Serial No. 275,874.

To all whom it may concern Be it known that I, TEMPLE C. SMITH, residing at East Orange, in the coimty. of Essex and State of New Jersey,have invent ed certain Improvements in Aerial Cable Guides, of which the followingis a specifica tion.

.- This invention relates to cable guides, and

more particularly to devices of this character which are adapted for use in connection with supporting and guiding cables in their passage from cable reels to aerial messenger wires, upon which they may be supported by means of rings or the like. 7

One of the principal objects of this invention is the simpler and more-expeditious placing of an aerial cable in position with decreased liability of injury to the cable than heretofore; while another object is that such cable placing operation may be efiectuated without the necessity of employing heavy, massive, complex or non-portable apparatus. Other and further objects of the invention will hereinafter appear.

in the accompanying drawing, in which like numerals represent like parts throughout, one form of the improved .device ap pears. Figure 1 illustratesa side elevation of the cable guide hooked at one of its ends to a strand, and adapted for movement in either direction thereon; Fig. 2 illustrates said uide in locked position on the strand, and h ig. 3 is a perspective view of the device showing its side plate opened.

The invention will now be described in detail in connection with the appended drawlhe frames in which the pulleys or sheaves, 1 and 2, aremounted comprise side plates 3, 4; and 5, 6. The plates 3 and 5 are provided at their upper extremities with a hooked portion by means of which the frame may be attached to a support such as a wire. Extending from and suitably attached to the lower ends of the side plates, 3, 5 and 4, 6 are straps 7 and 8. Reinforcing members 9, 10 and 11,12 are provided for said plates, and are fixed at their upper ends to the side plates 3, 5 and 4, 6, respectively. At their,

lower ends the reinforcing members are s'e cured together and to the bars 7 and 8. The side plates & and 6 with the bar 8, and reinforcing members 11 and 12, form a unitary frame structure which is adapted to be swung in apertures 01": the side plates away from its associated'frame to which it is hinged means of a plate l3 or the like. A member 14 associated with plate 13 is pro vided in juxtaposition to the hooked extremityor said plate 5, and the opposing edges of the members are cut away at such an angle as to allow the device to be readily placed in position on the strand, but when so placed to prevent it from becoming disengaged from said strand while in use. The plate 13 and member Ll are preferably secured together and to the side plate 5 by rivets or the like. T he laterally extending member is hinged at its other endby means of a'pin 15 or the I brought together and thus rigidly engage the strand, and prevent displacement of the de-, vice thereon, as will later. appear.,

The sheaves 1 and 2 are provided with the usual grooved peripheries, and are journaled on spindles 19 and 20. The spindles are introduced through holes in the center for the sheaves and are secured at one end. in apertures (not shown) formed in the side plates 3 and 5 and their associated bar 7. 'On their opposite ends the spindles are provided with plates 21 and 22 which are shrunk or otherwise attachedto said spin- I dies and serve to keep the sheaves in position thereon. The extrennties of the splndles project a su'dlcientdistance through the plates 21, 22 to engage and be supported in openings 23 and 2% provided in the members 4, 6 and 8. Thumb-bolts 25 and 26 engage with interior threads in the spindles 19 and 20, and when in place lock the laterally extending member. When the laterally extending member is raised, the sheaves 1 and 2 are retained in place on the spindles 19 and 20 by means of the plates 21 and 22 fixed to the spindles which are supported previously outlined.

When the improved cableguide isto be placed in position foroperation, it is at- 'tached to the messenger wirethrough a diagonal openingformed between the opposing faces of the hooked extremity of memher 5 and plate 14:, as be seen in Fig. 1. lVhile in this position the guide may be drawn back and forth along the wire until it-is in the proper place. Theother end of I the guide is then hooked to the wire and by means of the hand bolt 18, clamping plate 17 and side plate 3, rigidly grips the strand 1 and prevents longitudinal movement of the guide thereon. I

When the guide-is locked on'the wire,the

cable is drawn from'the cable reel over the sheaves '1-and'2 of said guide by means of a pulling in lineattached to the cable. "T he cable -is then threaded through rings or other supporting means on the w1re'a'ndth1s required operation continues until the length of'cable is in position. 1 c v After the cable isinplace the thumb bolts 25 and26of the cable guide are unscrewed ifromkthe spindles wand 20 and the lateral extending member, which is hinged to the plate 13 and yoke 16* is raised, as shown in Fig.3, and the cable is removed from guide.

this improved arrangement the Theguide may now be released from the 'wireby an operation which is practically the reverse ofthat previously described in.

connection with its installationcable is supported at different points while it is being placed in position on the wire by means of two small sheaves. The are thus formed by thecable is equivalent to an are several? times the diameter of'the sheaves, and thel-cable-when entering the rings, supported on the wire, at'this arcis'prevented from,.stripping off said rings. The varc formed .by said sheaves also allowsthe cable to enter said rings inas straight a line as is practicable, and permits the cable to be easily "pulled through the rings. =It will, therefore be clear that kinking or other excessive bending of the cable is prevented,

and itmay beplaced in. position with negligible injurylthereto and in an expeditious manner. V

I From the foregoing it is evident that the construction, operation and .many advam tages'of the herein described invention will beapparent to those skilled in the artwithout further description, i and it will be understoodthatthevarious changes in the size, shape, proportion and minor details of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.
